AECOM analysed the housing shortfall for 127 local authorities within 90 kilometres of central London in order to factor in commuting trends across the region and found that there will be a need for 2.5 million new homes by 2036.
But analysis of each local authority’s Strategic Housing Land Availability Assessment found there is an identified pipeline of sites for approximately 1.5 million homes.
"Limiting the conversation about the housing shortage to the GLA’s borders ignores the 700,000 people commuting into the city every day and the acknowledgment that London is the number one economic driver for the entire South East," said AECOM managing director for design, planning and economics EMEA Andrew Jones.
He suggested a "comprehensive programme of integrated growth strategies from the inner city through the region", adding that the homes required won’t be delivered if each local authority "is left to focus solely on their own needs".
"Throughout the region, we need to make the most of existing and future transport connections through intensified development around tube and rail stations, to create revitalised centres with homes, workplaces and community amenities fit for the city’s future demographic and economy," he said.
AECOM’s analysis also revealed that the population of this region is nearing 20 million, and is set to surpass 24 million by 2036.
